ABB 3BSE007286R1 DSTS105
Introduction to ABB DSTS105 3BSE007286R1 Digital I/O Fixture Module
ABB DSTS105 3BSE007286R1 is a digital I/O clip on module in the ABB AC800M distributed control system S800 I/O architecture. It serves as the core component for digital signal aggregation and distribution in remote I/O stations, responsible for connecting on-site switch signals to the control system and issuing control instructions to on-site actuators.
core positioning
This module itself does not have independent communication capabilities and must be installed on basic units (such as DSDP140B, DSDP160, etc.) or expansion racks to work, with communication and scheduling managed by the basic unit. It is the digital signal interface layer within the S800 I/O station, designed specifically for medium scale digital data acquisition and driving scenarios. Its channel density is higher than that of DSTS104, making it suitable for applications that require simultaneous processing of a large number of switch signals.

Main functional features
Fixture based installation design: Adopting a clip on structure, it can be quickly fixed on the basic unit or expansion rack without the need for additional terminal blocks, simplifying the on-site installation process and reducing the risk of wiring errors. Compared with screw fixed module installation, it has higher efficiency.
16 DI+16 DO channel configuration: Provides 16 digital inputs and 16 digital outputs, with a relatively high channel density among fixture modules in the same series. It is suitable for scenarios where a large number of switch signals need to be collected simultaneously and multiple actuators need to be driven, such as valve status acquisition and multi pump group start stop control.
Relay output characteristics: All 16 outputs are relay dry contacts, supporting AC and DC loads, especially suitable for driving inductive loads such as solenoid valves, contactor coils, indicator lights, alarms, etc. This is the key difference from transistor output modules – relay outputs can directly switch AC loads without the need for additional intermediate relays.
Loop monitoring: supports the detection of abnormalities such as input open circuit, output short circuit, communication interruption, etc. The fault information is reported by the basic unit to the main controller, and diagnostic data can be viewed through system software for quick positioning of the fault channel.
Status indication: Equipped with operation indicator lights, channel status indicator lights, and power indicator lights, it can quickly determine the working status of modules and channels on site without the need for additional diagnostic tools.
Electrical isolation: achieve ≥ 1500V electrical isolation between input channels, output channels, and communication ports, effectively suppressing the impact of on-site electromagnetic interference on the control system and improving system safety.
Parameterized configuration: Supports online configuration of I/O parameters through ABB dedicated industrial control software, including channel filtering time, etc. The configuration takes effect in real time, reducing downtime for debugging.
Hot plug support: Supports online hot plug replacement, maintenance can be completed without cutting off the power supply of the I/O station system, reducing the risk of downtime.
Start self check: Automatically check the electrical ID of the module when powered on, and do not enter the running state when it does not match the configuration, to prevent control abnormalities caused by mismatches.
Comparison with products in the same series
DSTS104 (3BSE007285R1) is an 8 DI+8 DO digital fixture module with half the number of channels, suitable for small-scale digital data acquisition scenarios. The core advantage of DSTS105 lies in doubling the channel density (16 DI+16 DO), which is irreplaceable in scenarios that require medium scale digital processing and relay output. DSTS106 (3BSE007287R1) is a 32 DI pure digital input module with no output channels. DSTD108 (5716000-ADB/1) is a 16 DI+16 DO digital connection unit, but it needs to be attached to the basic unit and does not use fixture installation. DSTS105 has significant advantages in scenarios that balance channel density, installation convenience, and relay output.
Typical application scenarios
Power industry: collection of switch values and relay drive for auxiliary equipment of generator sets, such as start stop control of feedwater pumps, fans, and coal mills.
Chemical industry: signal acquisition of reactor valve switches, driving of safety interlock relays, reducing the length of wiring from the site to the control room.
Metallurgical industry: remote I/O station digital signal access and actuator drive for equipment such as continuous casting machines and rolling mills.
Water treatment: monitoring and control of the status of multiple valves in the pump station, and driving of multiple actuators in the dosing system.
Manufacturing industry: Multi equipment status monitoring of production lines, multi-point sorting control of conveyor lines.
